The occupiers' burden: tackling food shortage and related health problems in post-war Germany 1945-47

The end of the Second World War brought much relief to its combatants, but a range of problems remained that would plague post-war Europe for years to come. Chief among them was food shortage. The breakdown of agricultural systems, essential services, and the state itself laid fertile ground for food shortage to develop in parts of post-war Germany occupied by the victorious powers. There is much to be gained from comparing the occupiers’ responses to this Horseman of the Apocalypse. The most fruitful comparison lies between the Soviets and British. Unlike the Americans whose economic might in the post-war period allowed them to better feed and supply Germans living in their occupation zone, domestic economic weaknesses hamstrung both Soviet and British responses to the more severe advent of food shortage which confronted them. Their responses were very different—some successful, others not—but all instructive for understanding the impacts of natural and policy factors on the development of food shortage and the consequences to the health of the population. The variety of these impacts have been obscured by the absence of this comparison in the literature, which is now made more feasible by the greater availability of the extensive resources that each occupier devoted to recording food and health data, particularly in the Soviet case. The data is not only relevant to the occupation period from 1945 to 1949, as it suggests long-term health impacts on those most exposed to the risk of food shortage then, and most at risk to the consequences of malnutrition decades later. In fact, as the available data defines regional differences in food rations and, accordingly, comparative food shortages in Soviet and British occupation zones, the situation in post-war Germany provides an excellent platform for future research linking differences in early nutrition to adult health outcomes.

Correlação entre a qualidade de vida, classe funcional e idade em portadores de marca-passo cardíaco

OBJETIVO: Avaliar se existe correlação entre qualidade de vida e classe funcional em pacientes no pós-implante de marca-passo cardíaco, e sua relação com idade. MÉTODOS: Investigados 107 pacientes de ambos os sexos (49,5% do sexo feminino e 50,5% do sexo masculino), tempo médio de implante 6,36º ±2,99 meses e média de idade 69,3º ±12,6 anos. Para avaliação da classe funcional, foi utilizada escala proposta por Goldman e para qualidade de vida, questionário AQUAREL associado ao SF-36. Realizada análise estatística pela correlação de Spearman, com significância de 5%. RESULTADOS: Foram observadas correlações negativas entre qualidade de vida e classe funcional: AQUAREL nos três domínios, desconforto no peito (r=-0,197, P=0,042), dispneia (r=-0,508, P =0,000), arritmia (r=-0,271, P=0,005) e, no SF-36 nos oito domínios. em relação à idade, correlação negativa com Capacidade Funcional do SF-36 (r=-0,338, P=0,000) e não se observou correlação com AQUAREL. Entre idade e classe funcional observou-se correlação positiva (r=0,237, P=0,014). CONCLUSÃO: Neste estudo, encontrou-se correlação negativa entre qualidade de vida e classe funcional, evidenciando nesta amostra que os pacientes pertencentes a melhor classe funcional apresentaram melhor qualidade de vida. Conforme maior idade, pior a qualidade de vida em Capacidade Funcional e em classe funcional. Sugere-se, que idade e classe funcional influenciam qualidade de vida e as escalas de classificação funcional podem constituir um dos instrumentos que integram a avaliação e refletem a qualidade de vida em portadores de marca-passo.

Riscos para o excesso de peso entre adolescentes de diferentes classes socioeconômicas

OBJETIVO: Analisar a associação entre fatores de risco e a presença do excesso de peso entre adolescentes de diferentes classes socioeconômicas. MÉTODOS: Análise transversal, da qual participaram 888 jovens de ambos os sexos e com idade variando entre 11 e 17 anos. O índice de massa corporal foi calculado por meio dos valores de massa corporal e estatura, e utilizado como indicador do excesso de peso. A atividade física, a ingestão alimentar e a classe socioeconômica (alta e baixa) foram analisadas mediante a aplicação de questionários. Os dados foram analisados estatiscamente por meio dos testes Qui quadrado e regressão logística binária. RESULTADOS: Para os adolescentes de classe socioeconômica baixa, uma inadequada ingestão alimentar (Razão de chance [RC]= 4,59) e o sobrepeso dos pais (RC= 5,33) foram associados à presença do excesso de peso. Entre os adolescentes de classe socioeconômica alta, a escolaridade materna (RC= 0,57), estudar em escola privada (RC= 3,04) e o sobrepeso dos pais (RC= 3,47) foram associados à presença do excesso de peso. CONCLUSÃO: em ambas as classes socioeconômicas, o sobrepeso dos pais foi um importante fator de risco associado ao excesso de peso. Os outros fatores de risco diferiram entre as classes socioeconômicas.

Synthesis and electrical characterization of tungsten doped Pb(Zr0.53Ti0.47)O-3 ceramics obtained from a hybrid process

Pure and W-doped PZT ceramics (PZT and PZTW) were prepared by a hybrid process consisting in the association of polymeric precursor and partial oxalate methods. The phase formation was investigated by simultaneous thermal analysis (TG/DSC) and X-ray diffraction (XRD). The effect of W doping PZT and their electrical properties was evaluated. Substitution of W by Ti leads to an increase of Curie temperature and broadening of dielectric constant. A typical hysteresis loop was observed at room temperature and the remnant polarization was increased with the content of W. (c) 2007 Elsevier B.V. All rights reserved.

Dielectric and fatigue properties of Pb(Zr0.53Ti0.47)O-3 thin films prepared from oxide precursors method

Fatigue is an important problem to be considered if a ferroelectric film is used for non-volatile memory devices. In this phenomena, the remanent polarization and coercive field properties degrades in cycles which increase in hysteresis loops. The reasons have been attributed to different mechanisms such as a large voltage applied on ferroelectric film in every reading process in Ferroelectric Random Access Memory (FeRAM) or memories for digital storage in computer, grain size effects and others. The aim of this work is to investigate the influence of the crystallization kinetics on dielectric and ferroelectric properties of the Pb(Zr0.53Ti0.47)O-3 thin films prepared by an alternative chemical method. Films were crystallized in air on Pt/Ti/SiO2/Si substrates at 700 degrees C for 1 hour, in conventional thermal annealing (CTA), and at 700 degrees C for 1 min and 700 degrees C 5 min, using a rapid thermal annealing (RTA) process. Final films were crack free and presented an average of 750 nm in thickness. Dielectric properties were studied in the frequency range of 100 Hz - 1 MHz. All films showed a dielectric dispersion at low frequency. Ferroelectric properties were measured from hysteresis loops at 10 kHz. The obtained remanent polarization (P-r) and coercive field (E-c) were 3.7 mu C/cm(2) and 71.9 kV/cm respectively for film crystallized by CTA while in films crystallized by RTA these parameters were essentially the same. In the fatigue process, the P, value decreased to 14% from the initial value after 1.3 x 10(9) switching cycles, for film by CTA, while for film crystallized by RTA for 5 min, P, decreased to 47% from initial value after 1.7 x 10(9) switching cycles.

Effect of type of cuttings and indolbutyric acid on the rooting of rose (Rosa sp. 'Red success') leafy cuttings during two seasons

The objectives of this study were to evaluate the effect of type of cuttings (apical, intermediate and basal) and different concentrations of IBA (indole-3-butyric acid) on rooting of Red success rose (Rosa sp.) leafy cuttings, during two season of cuttings collection (summer and winter). The investigation was carried out in the farm Irmaos Van Schaik in Holambra-SP, Brazil, from February to April and August to October/1993. The experimental design was a randomized block in a factorial arrangement. It consisted of 12 treatments (3 types of cuttings combined with IBA powder in 4 different concentrations - 0, 1000, 2000 and 4000 ppm) with 3 replicates during 2 seasons. The investigation permitted the following conclusions: the apical and intermediate cuttings showed better results in general when compared to the basal ones in both seasons; the average rooting at the transplanting time were 76%, 70% and 47% (summer) and 80%, 69% and 33% (winter) for apical, intermediate and basal cuttings, respectively; the utilization of IBA did not stimulate rooting. The average rooting for the control cuttings reached 85% (summer) and 78% (winter), regardless the type of cuttings.
